SADDLE FOR THE TOP R OLLS OF SPINNING-MACHINES.

Specification of Letters Patent.

Patented. May 29, 1906.

Application filed November 18,1905. Serial lTor 287,959.

To all whom it may concern.-

Be it known that I, WILLIAM RAINVILLE, a subject of the King of GreatBritain, residing at Woonsocket, in the county of Providence and Stateof Rhode Island, have invented new and useful Improvements in Saddlesfor the Top Rolls of Spinning-Machines, of which the following is aspecification.

My invention pertains to saddles for the top rolls of spinning-machines;and it contemplates the provision of a saddle which in addition to beingsimple and inexpensive and well adapted to withstand the usage to whichsuch devices are ordinarily subjected is constructed in such manner thatall that is necessary in order to place pressure on or remove pressurefrom the middle roll is to reverse the saddle.

Other advantageous features peculiar to my invention will be fullyunderstood from the following description and claims when the same areconsidered in connection with the accompanying drawings, forming part ofthis specification, in which- Figure 1 is a side elevation of so much ofa spinning-machine as is necessary to illustrate my invention with mynovel saddle in position to press on the middle roll. Fig. 2 is asimilar view with the saddle reversed to remove pressure from the middleroll, and Fig. 3 is a front elevation with the saddle arranged in thesame manner as in Fig. 1.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which- A is the front roll, B the middle roll,and O the rear roll, of a spinning-machine.

D is the body of the saddle constituting the present and preferredembodiment of my invention.

E is the spring of the saddle, and F is the rod for connecting thesaddle-body with the ordinary weighted lever, which latter I have deemedit unnecessary to illustrate.

The saddle-body D is formed of one piece of any material compatible withthe purpose of my invention and comprises a longitudinal portion a,adapted to bear on the rear wall 0 and having ducts b at intermediatepoints in its length for supplying the rear and middle rolls withlubricant and also having seats 0 in the lower and upper edges of itsforward portion for the adjustable connection of the rod F and a head (1extending in oppo site directions from the forward end of thelongitudinal portion and having concave bearingse at its ends and alsohaving a lubri cant-duct f extending throughout its length and betweensaid bearings e.

The spring E is fixed at one of its ends to one edge of the longitudinalportion a of the body D at an intermediate point in the length of saidportion and is arranged, as shown, so as to exert pressure on the middleroll B when the. saddle is in the position shown in Fig. 1 and leavesaid middle roll free from pressure when the saddle is reversed, or inthe position shown in Fig. 2.

As is well known in the art, it is necessary in some cases to imposeweight or pressure on the middle roll of a spinning-machine and inothers to relieve the middle roll of weight or pressure. Now when mynovel saddle is employed and it is desired to relieve the middle roll ofweight or pressure the same can be accomplished by simply reversing thesaddle i. e., turning the same on its axis from the position shown inFig. 1 to the position shown in Fig. 2since when this is done the s ringE is placed uppermost and away from tiie middle roll. When, on the otherhand, it is desired to subject the middle roll to weight or pressure,the saddle can be readily restored to the position shown in Fig. 1, withthe spring E bearing on the said middle roll.

I claim 1. A saddle for top rolls comprising a body having alongitudinal portion and a head extending in opposite directions fromthe longitudinal portion and provided at its ends with bearing portions,and a spring carried by the longitudinal portion of the body and adaptedin one position of the body to exert pressure or weight on the middleone of the top rolls.

2. A saddle for top rolls comprising a body having a longitudinalportion provided with lubricant-ducts and seats at the lower and upperedges of its forward portion and also having a head extending inopposite directions from the forward end of the longitudinal portion andprovided at its ends with concave bearings and also provided with a myhand in presence of two subscribing Witduct extending between saidbearings, and a nesses. spring carried by the longitudinal portion ofthe body and adapted in one position of the WILLIAM RAINVILLE' 5 body toexert pressure or Weight on the mid- Witnesses:

die one of the top rolls. GEO. W. SIPAUIJDINQ,
